What is patch testing in skincare?Updated a year ago
The term “patch testing” is usually a medical one, referring to a category of allergy tests carried out by dermatologists or allergenists. In skincare, there’s a simplified version of patch testing that ensures new skincare products won’t irritate the skin or clog pores. That’s what we call a skincare patch test.
The skin patch testing process is fairly simple. You apply a product to a patch of skin for several days in a row and see what happens. If all goes well, the product is probably safe to apply to your face. If you experience signs of irritation, you know that this product isn’t for you.
